Canon has announced updated firmware for the EOS 5D Mark III. Firmware v1.1.3 makes an unspecified change to accommodate the EF40mm F2.8 STM pancake prime lens announced earlier this month. Beyond this, the update fixes a series of bugs and corrects a series of linguistic errors in menu screens. The firmware is available for download from your local Canon support site now.

Firmware Version 1.1.3 incorporates the following improvements and fixes:

Supports the single focal length EF40mm f/2.8 STM lens that is to be released at the end of June, 2012.

Fixes a phenomenon in which an image may become underexposed when using the Auto Lighting Optimizer for continuous Auto Exposure Bracketing (AEB) shooting.

Fixes a phenomenon in which the backlight of the LCD monitor may not turn off depending on the camera settings and timing.

Fixes a phenomenon in which the camera's power may not turn on when a super-telephoto lens *1 is mounted to the camera with an extender*2. *1) EF 300mm F2.8L IS II USM / EF 400mm F2.8L IS II USM *2) Extender EF 1.4X III / Extender EF 2X III

It does NOT support all the features of the 40mm STM lens. Specifically, it doesn't support continuous autofocus in video mode. If Canon knew they had this lens in the pipeline, WHY did they not include the Hybrid AF in the 5D3?? What is the point of a full-frame lens with continuous autofocus in video if NO FULL-FRAME BODY SUPPORTS THE FEATURE??

Because no serious videographer will use autofocus. The 5d mark III is aimed at profesionals. Both photographers and movie makers. So a feature like autofocus during movies is normal on entry level bodies, but not on this. Autofocus in movie mode uses Contrast detection and it is not possible to have a smooth focus that will even get close to professional expectations. You can use a USB follow focus to focus easily, it let's you do focus switches with the exact speed you want and much more...

Well, this simply confirms one of my earlier posts - the 5d Mk3 is already out of date as regards AF (which of course we all knew) and shows that like SONY Canon have different design teams working on different products WHO DON'T SPEAK WITH EACH OTHER - otherwise the 5d Mk3 would have been ready for the new 40mm lens...which I still think is a stupid focal length having owned the Pentax 40mm back in the 1980s' Why oh why didn't Canon take this opportunity to introduce a new 35mm lens ? The current ones are 35 F2 - good lens, but SLOW old AF and the 35mm f1.4 L - lovely but for too many users far too expensive.

never heard of software 'features' before. Do the math to determine every possible variety of illogical operating conditions with every possible hardware set that a consumer can apply to a camera and you will see why things get through.

jeeezus! why are ppl so blind and ready to say crap to defend brand B or A???

(before any ppl call me nikon lover/or hater or whatever, let me say that for more then a decade my choice has been Canon!BUT that doesn't mean i'm their blind fan like from a football club! Neither is this Religion- a question of faith!_ THIS IS SIMPLE, WORK, OR DOESN'T WORK EQUIPEMENT SITUATION!!!Are you going to excuse them also when the 1d mkIII was released with problens in the autofocus!?! Really? A sport's camera?

Give me a brake people, and instead of saying silly things on the web, GET OUT AND TAKE GOOD PICTURES!!!

That's WRONG. I just called Canon tech support and the new 1.1.3 firmware only supports lens corrections, it does NOT support continuous autofocus with the 40mm STM. You need the Hybrid AF for that and the 5D3 doesn't have it. You were either given bad information or you misunderstood.

Because it is a new lens. Not only optically speaking, so any lens corrections that the 5D MkIII has baked in would need to be added for it, but also possibly because this particular lens uses a type of motor to drive the autofocus that Canon have not previously used. This might mean that the camera needs to treat it differently when focussing.

Well it's entirely possible I'm wrong about one or both of my suggestions, I am just guessing after all. I'd say that the most likely of my two theories is that it has to do with the software based lens corrections, which no other Canon camera has, making it a pretty safe bet that the update affects that.

Because, unlike previous cameras in the range, the 5D3 has enough processing power to apply corrections in-camera. Hence, for each new lens they release, they will need to update the firmware so that the corrections can be applied correctly. There now, wasn't that difficult to understand was it?

No, the 0.1% of owners who use it in long-exposure, low-light situations where the problem would occur, and who are unable to compensate for that in post, can get the tape they need from any department store.

my 40mm F/2.8 has been working fine with 5DM2 and 7D..,,, does it actually ad the AF during video ability? Also what do you guys mean "to be released at the end of June" the lens has been on sale at US Biggest Retailer - Best Buy since Sunday, the 17th.

Phenomenon is a Latin word and means something "unexpected":MW Unabridged; a : a fact or event in the changing and perceptible forms as distinguished from the permanent essences of things: as (1) : a mutable, caused, or developing aspect of things as contrasted with their fixed and substantial natures (2) : a perceptible aspect or appearance of things as contrasted with their true or ideal being (3) : an object of sense perception as distinguished from an ultimate reality (4)

Clearly I'm not going to dispute that. But it's also a relatively neutral term - there isn't the assumption that a phenomenon is positive or negative. In a situation in which the LCD won't turn off in certain (presumably rare) circumstances, although it wouldn't be incorrect to call it a phenomenon, it could appear somewhat disingenuous, as it suggests it's just something that happens, not a problem.

As such, it's quite reasonable for Canon to call it a phenomenon but any attempt to impartially report the problem should probably use a term that calls a problem a problem. Hence we used the term 'bug.'

It's not the first camera to be updated shortly after launch, and I'm sure it won't be the last. I seem to remember that there was one camera that was updated before the camera itself was widely available.
